Abstract :

In this paper, we studied the interaction of heat transfer with peristaltic pumping of a Williamson fluid through a porous medium in a planar channel, under the assumptions of low Reynolds number and long wavelength. The flow is investigated in a wave frame of reference moving with velocity of the wave. The perturbation series in the Weissenberg number (We $<$1) was used to obtain explicit forms for velocity field, pressure gradient and friction force per one wavelength. The effects of Weissenberg number We, Darcy number Da and amplitude ratio $\phi$ on the pumping characteristics and heat transfer are discussed through graphs in detail.
